摘要:

用第4 代新版丰田人体模型THUMS (Total Human Model for Safety),分析研究了正面碰
撞对于乘员人体模型的头部、胸部、腿部的伤害。基于国内某款运动型多功能车(SUV) 零部件试验和
正面碰撞试验,利用动态非线性显式有限元方法,建立了有限元约束系统模型,用Hyperworks 软件
作为前后处理器,用动力学分析软件LS-Dyna 为求解器的仿真模式。结果表明:该款THUMS 人体模
型头骨最大压应力2.4 MPa,颅内压应力44 kPa,头部无损伤风险;股骨、胫骨最大应变0.4%,左右
十字韧带应变3.6%,腿部无损伤风险。上肋骨应变大于3%,胸部压缩量达到30 mm,造成胸部简明
损伤等级三级(AIS3)的概率为30%。因此,该碰撞工况下最有可能受伤的部位是胸部。

Abstract:

Evaluation analysis research was carried on the head, chest, and leg hurt of occupant body in
frontal crash by using a human body model, the fourth generation THUMS (Total Human Model for Safety).
A finite element model (FEM) of restraint system was established using a dynamic nonlinear explicit finite
element method based on a domestic SUV (sports utility vehicle) component test and frontal crash test with
a Hyperworks as processor and with a dynamics analysis software LS-Dyna solver for simulation model. The
results show that the head of the THUMS human body model has no injury risk with the skull maximum stress
of 2.4 MPa and the intracranial pressure of 44 kPa; And the legs have no injury risk because of the maximum
strain of 0.4% for both the femur and the tibia, and the strain of 3.6% for right and left anterior cruciate ligament.
The rib strain is above 3% with the chest compression up to 30 mm, these make a 30% probability of AIS
(abbreviated injury scale) damage grade level 3 for concise chest. Therefore, the chest injurie has the most
possibility in the collision condition.
